My invention relates to nail-distributors, being particularly concerned with'the pre venting of the escape of nails or like fastenlngs from a drum contain ng amass from.

5 which delivery is to be made.

The nail-drum of a" distributor is come monly closed at the outer or rear side dur-- ingoperation, but at theinnerrside has an openingthrough which extend two nail-conjveyors one of thesebeing the raceway-structure or washboardreceiving'nails from the drum and forwarding them to the discharge device, and the other the chute by-which nails wasting from the raceway are. returned to the drum to be again delivered. Some of the nails dropping from the drum-buckets upon which they-are elevated for delivery to the raceway tend to be so deflected that they escape through the opening and fall upon thefloor. To confine the nails'to the desired paths within the supplying system is an objeotofmy invention.v This): accomplish byzthe pro vision of a guard-plateior' the drum-opening, and inwhich is an opening or openings forf one or more nail-conveyors, this plate being arranged in close proximity to the drum-wall about'the opening thereinand so mounted as to permit its adjustmenttoward and from the drum. By this means,the opening in the drum may be almost entirely closed, save where the nailaconveyors pass through it, the closure at the meeting plane of the drum-wall and guard-plate being perfected by the adjustment of the latter upon its mounting. To enable this to bring about conf formity under varying structural andsup porting conditions of the drunntheplate may have both bodily and angular adjustment. As herein illustrated; a compound adjustment is obtained by pivoting the guard-plate i upona pin which may beplace'd in different positions laterally and clamped. Aretai'n: ing means in the form of a brace is preferably employed to aid. in holding the guardplate. However the plate is "mounted, the ef:

ficacy of the closure may be increased bythe use of a nail-defiectingfiange extending into the drum about thesurface with. which said plate co'-operates,and one or more auxiliary plates maybe carried by the guardrplate over thefioor, are usuallyswept up and away, causinga" substantial loss. V

' Toifprevent the wasting of nails in this manner, lclose the greater part of the opena portion of aconveyor-opening therein, this auxlliaryiplate be ng variable in position.

"The accompanying drawings show one of the several possible embodiments of my in vention, I v I Fig. 1 being a broken side elevation of that portion of a-nail distributor of which my invention isa part;

Fig." 2, a transverse sectionf'on the line Fig- 3, abroken detail, partly in section and partly pivots; and

Fig. 4, an enlarged section on the line 1,005,302.,P0 e, October 10, 1911. Of this there appear in the drawings portions of a -l:'ra1ne '10, a washboard or a nail-wayv 12 0scillating thereon, and parallel horizontal spindles 14,.14'fiX ed in the frame and upon which rotate rollslfi, 16. These rolls have grooves 18 and surfaces 20 spaced'it'rom said groovesgtosupport, by peripheral flanges 22, 22, the'front head24and rear head 26 of a nail-drum 28. Gearing 29 rotates the rolls,

which act frictionally to turnthe drum. A

mass of'Knails{containedin this drum is elevated by buckets spaced about its interior but not illustrated in the drawings, and dropped upon the nail-way, which retains aportion of them while others fall to the bottom ofthe drum to be again elevated. In the forward travel of thenails: down the nailway to a discharge device'such as that of Pope, some fall therefrom or waste into a "chute 30, which directs them back to the sup? ply in the drum; In this elevation, descent,-

advance and return'of the nails,theyytend to be deflectedthrough the opening at the in nerside ofthe drum, which permits the passage through the head'24 of the nail way 12 and'the chute 28. These nails, falling upon thrown ingin the head 24 by a guard-plate 32; This in elevation, of one of thedrumso i plate is shown as circular and adapted to be positioned in close proximity to a surface 3% lymg substantially at right angles to the axis of rotation of the drum and surrounding the opening. Since the manner in'which the nail-drum is supported and rotated and its commonlyrather inexact construction render uncertain the location of the surfacetid, a mounting is provided for the guard-plate which permitsit to be positionedinap-proxi'mate parallelism and in close proximityto the drum-surface. A suitable form of mount ing is provided by spaced lugs 36, 36 =projecting horizontally from near the bottom edge of the plate and cooperating'with vertical lugs 38,38ruponthe frame. Screws 40,.be-

neath the. heads of which .are washers .42, pass through openings. 44: inthe. frameelugs, these openings beingofconsiderably greater di ameter than the screws. The inner ends of these screws are threaded into .the. plate-lugs. Thisma-nner of connection allows the guardplate to be swung upon the screws as. pivotpins .to-conform angularly to the surface 3d ly retain the upper part. of the-plate :at the edge opposite the pivotal mounting against displacementfrom its adjusted position, it is ,preferablyjoined bya, diagonal brace 46"to the frame. To permitasingle bracing memberxto" be employed. for all positions of the plate, .the connections 48 and450 between the braceand the frame andplate, respectively maybe of .the slottand-screw type. The slot of theconnection-AS lies in azsubstantially horizontal plane. and thatofthe connection 50 in a substantially. vertical plane. By shifting oneor the other of.these, the brace may betadapted tosall .plate fadjustments. To more certainly preventnails from enterin' thes space between the. guard-plate and drum-surface 34:,1 have. shown afiange 52 formed-integrally with the plate and-sur- 1O1llTLCll-I1g;tll.bllt the upper portionof the drunvopening. Nails falling toward the space will strike. the flange and be deflected baekainto thedrume In the guard-plate 32 are two 'openings,-to receive, respectively," the nail-way 12. and the. returnechute 30.; Because ofthemovementofthe plate forndjustment, and since the dimensionsio-f the elements, especially'the sheet-metal chute, are uncertaimal may= provide one or more auxiliary plates-for attachmentto theaguard-p-late over the conveyor- 0pe-n-ings. These plates. appear at 54, 54 .as

angular, to conform. to twoadj acentsides of the conveyor with which they co-operate. Theyhave openings 56 to receive attaching screws 58 of'less diameter than the openings and threaded into the plate 32. By these connections, the plates 54 may be secured as close to the conveyors'as is possible and still avoid interference.

It will be seen that, by this arrangement, all the openings in the delivery side of the distributor-drumare effectively protected against the accidentaldischarge of'nails and 2..In.a nail-distributor, the combination withnrotatabledrumhavingan opening, of
